What is missing, in my view, are the distinctive shapes of the two predecessors, such as the large triangles, the cross or the parallelogram. Previously you had to think as how I build these special forms at all meaningful in the figure, if it is still space for the remaining smaller parts. That now falls away. For now it is mostly mere trial and error, trial and error, to fill the many empty space with the rather small, somewhat spidery hexagonal shapes. It also somehow missing the wow factor when designing the levels, many resemble each other except for 1 or 2 fields but very, as you would have quiet can give a little more effort in my opinion.
All levels can be selected individually As with the predecessors and you can also make unlimited giving tips. However, each tip will cost a jewel and can be seen afterwards in the Level Index, which level has been solved without any help (= 3 ***) or only with tips. How long it takes does not matter, you can take your time. The background sound is harmonious, but a little repetitive and can be shut off. Regularly ask the app as it did in parts 1 and 2 to a vote, I felt as intrusive.
Overall a (still) good game, ideal for in between times to toss a few minutes relaxing. Durable game motivation does not arise for me because of the lack of variety and the monotonous level design but one. True fans of the genre will probably over but can easily be overlooked. On a positive note that the app does not require authorization requirements.
